In the legal field, alienation is called the donation, delivery or assignment of real rights over a movable or immovable property to another person, whether natural or legal. In a strict sense, this would refer only to domain rights, while, in a broad sense, it is about the transfer of both domain rights and other rights, such as exploitation. Similarly, alienation is also called the transitory loss of senses and reason, product of intense emotions, such as anger, anger or pain.

As a judicial concept, alienation focuses on the so-called domain rights or real rights. These are the ones that give a person the quality of owner of a certain good, being, then, free to do any type of activity with it, as long as they are not branded as illegal. In general, alienation is used when there is a case of theft or, well, there are debts between those involved. Thus, the alienation can be a compulsory activity, as a result of orders issued by judges, because alienations occur when, voluntarily, an individual decides to put some of his belongings, such as cars or houses, up for sale, and the transaction is finalized. .

Mental derangement, for its part, is also present in legal books, since that is how criminals suffering from unstable mental conditions are called. In this way, the treatment that should be given to them, due to their condition, should be different, regardless of the crimes they have committed.
